Thinking wild,
like in linux we can have live cd & boot from a live cd is it possible to make the android rom compatible for booting from internal or external sd card without installation?

This way we can test different roms without messing up the installed rom, the latest such implementation was done in 2009 for canon 5D camera & later for many other cameras having magic lantern firmware to boot from CF/SD card without messing up the firmware.

Any developer willing to look into this?

There are already such a thing called boot manager. It support multi-ROM installing. But only for HTC devices, even not Samsung I9000.

Idea is fantastic. It looks like 'preview of rom' just like 'theme preview' in nokia. But practically its impossible. U can use emulator to run rom on computer.

Oh I didn't know that that boot manager exist can you give me the link for this please.
Are samsung chips locked in some way hence now allowing the booting?

We need first USB OTG.
Like SGS2, but there we have a "hidden" partition, that is the second boot partition!

Ok found the boot manager in the market & the description says
Quote:

BootManager will not work with Samsung devices that are not listed because of the way Samsung handles the boot partition (probably hidden).

No samsung device is listed only HTC work. Seems samsung purposely locking the devices & crippling the phones even though hardware supports many features?

Yes kind of dual boot like on my windows machine I still can boot into linux from the live cd, it will be ideal if android roms can be made to work like that but I am no developer & don't even know how this can be done hence inviting all genius rom developers to look into this possibility.

Developers will get a lot more feedback from users since then we could test roms (nightly build) as & when required without installation & messing up the stock rom.

Great idea, but very difficult to achieve. But i'm very positive that with the presence of some great devs we have here one day we can achieve such feat.

This is a good way of eliminating having to flash new ROM on our devices.
