transmission DOES work, saying it doesn't is simply wrong however you try to justify i!
the program itself won't make your memory unreadable, the nature of how p2p programs download and write data to flash memory will eventually corrupt a block, and then the n900 will assign it as read only when it detects corruption, this is why you should always set a p2p client on a flash memory system to save to removable rather than main memory. flashlite does look like a good viable solution, however claiming it is necessary is wrong. it will work without, on an sd card or n900's main memory if you so choose.
