COSIGN: implement cosign cgis as php?

[kevin mcgowan <clunis@xxxxxxxxx>]

cosign.cgi (responsible for LOGIN, CHECK, & REGISTER) and logout 
(responsible for, you guessed it, LOGOUT) are both CGIs written in C.  
These work well and perform fine on our servers under all but the 
heaviest loads.

What would you think about rewriting these CGIs in PHP -- strictly for 
enhanced performance/load resilience?  Would a dependency on PHP on the 
weblogin server be a deal breaker for anyone considering the use of 
Cosign?  Would it make installation of the weblogin server too 
complicated?  Is there anyone for whom this change would be a great 
positive?  Note that we're not considering doing it anytime soon -- I'm 
just trying to gather opinions.  Would mod_fastcgi support be more or 
less appealing than using PHP?  mod_perl?  rewriting the CGIs as an 
Apache module?

I should note for completeness that PHP is already required by 
'friend.'  Anyone using the friend guest account functionality is 
likely to have to install PHP anyway.  What I'm asking about is this 
idea of requiring PHP for the core functionality.
