Good luck. FWIW: I have a system to produce a monthly statement and bill 
out of the raw asterisk CDRs for a small residential home entirley in
PHP.. It wasn't hard, although it doesn't store long-term logs - they're 
handled elsewhere.

Shouldn't have to hope at all.

One of my embedded systems:

dsx# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/ram0             136M   70M   66M  52% /

the top of 'top':

top - 00:54:08 up 2 days, 50 min,  1 user,  load average: 0.00, 0.00, 0.00
Tasks:  28 total,   1 running,  27 sleeping,   0 stopped,   0 zombie
Cpu(s):  0.0%us,  0.0%sy,  0.0%ni,100.0%id,  0.0%wa,  0.0%hi,  0.0%si,  0.0%st
Mem:    257172k total,   190324k used,    66848k free,     1936k buffers
Swap:        0k total,        0k used,        0k free,    30744k cached

This is running on a VIA processor - the entire system runs in RAM and as 
you see takes up 70MB. I could probably make the whole thing run in 128MB, 
but it's easier in 256MB (of which 140MB is a ramdisk) This is a cut-down 
Linux, but not that cut-down. No busybox, or uClinux. Runs apache+php, 
asterisk and perl.

Running the code out of 256MB of Flash with 64MB of system RAM should be 
trivial.
