In fact ...
I just found ...doing some light hunting...
these so far...

fairly thorough, comprehensive but intensive. In the end though it means having essentially whatever distro (that could conceivably work) packed with say....ALL the pre-set-up enviros for the 770, n8x0, n900, etc...on a (persistent rolling release even...meaning the master copy really wouldn't need redoing unless particularly installed enviros changed...big plus) liveusb ...forget a livecd or livedvd structure...just not big enough.
hm..

and this for linux mint...wonder if it would work with debian edition ...

going to look and read some more...
if I find any other interesting tidbits I'll mention it here...

here is an intriguing method caught my eye...
clone your fresh-clean-bare-normal operating system into your v.m
tweak it into maemo-enhanced-perfection safely in said virtual machine.
then turn it into a distributable iso ...
hand them out to everyone.
they just burn it on their own cd/dvd/usb/sdcard and..
voila! instant bootable live medium maemo-goodness

hm..y'know..as a side note...I just thought ...
isn't mer installation on pc meant for a vm enviro only?
that puts an interesting spin on things...
possibly having mer running as a bootable live running distro on a usb, dvd or card. THAT I'll have to try...

addendum...ach Cop ...live distros are simplicity personified nowaday.
and they are built to run on pretty much anything.
crap I've played with so many of them...
I've put then on usb sticks, sd/minisd/microsd cards and run them...
persistence...though...is such a grand thing. writing your stuff to the liveusb so it remembers...retains everything from when you were last working with it. No more just shutting off and starting up to an scrubbed clean.. erased (of end-user changes that is) liveusb.
I just never thought before of packing up a normally installed distro with maemo devel enviros. and then turning it all into a persistent rolling release liveusb .
edit: yeah i did forget an eensy-weensy thing about -" took 2-3 minutes to load the whole DVD to RAM, and once it was done, it was faster than using a USB stick since reading/writing to RAM is faster than reading/writing to USB stick" to quote someone who tried both a liveusb and livedvd...
also I forgot that with persistence enabled on a liveusb alot of reading/ writing goes to the usb stick...meaning the usb lifespan is lessened...alternative is to make copies onto other usb sticks as failsafe backups..which seems a sane precaution anyway...or disable persistence when not required...even simpler solution...thereby lengthening the usb stick lifespan to a normal time and yet be able to utilize say a 32gb (or greater) usb stick capacity instead of a 4 gb re/writable dvd capacity...which makes a great deal of sense considering that the intent is to have devel enviros on a live medium ...hence the more space available the better.
....and on some my personal fav's like epidemic, kaos, semplice, lmde ... ...considering the nature of this exercise... and across-the-board end-user friendliness ...compatibility with maemo devel enviros...and all around distro health and stability ...I would lean toward something like lmde...pretty stable compared to others... as far as r.r.'s go
It would be grand to just do it on normal ol' 'buntu or debian ...most are familiar with that..but ...in no time we'd be back in the same sticky-spot we are now...the livecd/dvd/usb would be outdated again...not really something I would savour doing every couple of years...
Hm...I think I'll set up lmde in a v.m. and see what I can pack it with...
then see how it works out as a live-whatever..as well I think I'll set up mer and try the same...

edit: for starters the links here at tmo for mer-x86-generic-image-anything is shot.
edit: scratch that think I found something.
