you can use exec module to execute an external command (kamctl ... or 
kamcmd ...). Also, utils or some embedded interpreter can be used to 
make http requests (to xmlrpc).

On the other hand, pipelimit (which is intended to be more dynamic), got 
the option to define pipes dinammicaly. Adding support to change the 
limit should be easy -- I will look into it if nobody else sends a patch 
meanwhile (and could be better to add a feature request on tracker, not 
to forget about it) -- however, it is only in devel version.

Cheers,
Daniel
