detection when web server/ftpserver/any server/ is running on a non

Not yet, but we're working on it. It may take us a bit though until  
this is ready for productional use as it requires significant  
internal changes.

(Doing just \*detection\* is rather easy using signatures; the  
\*decoding\* part is the tricky one).
