I noticed, but i dont have patches, just hacks, that might well
break stuff, (but it seems to work ok). I think it would be much
cleaner to do a proper port of ppp2.4.0.

If anyone wants the code i currently have i can mail it directly
(it does work, but its untested on anybody elses kit).

My ideas are for a pretty full filesystem, it would provide a proper
abstraction layer in the same way that imfs does (i.e user would just do
read/write etc). I was not going to do any caching i was just going to lock
device and have the user re-try (during the erase),..)

But i have got a quite well defined allocation methord. If you could send,..
me the guidelines and and plans you have i will add what i can.
