[lcdproc] Not in perl...

It is also true the other way round.  I am exclusivly a perl developer, I do
not do C.

I though there was an lcdproc library that did all the fun stuff.  If that
is the case we can write an XS wrapper and module such that interfacing to
lcdproc is a dream.

Rubbish.  Poorly implemented perl is big and consumes memory.  Poorly
implemented C simply core-dumps ;)

Perhaps this is true in your case - but I have yet to find production code
which I have found un-readable (unless someone was aiming for an obfusication
contest).

Perl is a higher level language and as such:
1)	Should be more readable.
2)	Should have shorter developement times.
3)	Should be easier to debug.

4)	Slower than C.
5)	Probably uses more memory.

C on the other hand:
1)	Less readable (more code required to do simple tasks)
2)	Development times are longer.
3)	Harder to debug
4)	Have to guard against memory leaks, meandering out of bounds etc...

5)	Faster
6)	If written well will be smaller.

Note about memory usage...  If your user uses a shared perl binary then
memory allocation is near enough non-existant for the interpreter/compiler
and the memory arguments probably don't apply.
