igrep on remote files with tramp?

[Daniel Berdine]

I need to work with files on a remote server, and tramp so far has 
seemed the best way to get the job done. However, I would very much like 
to be able to use the igrep functions, in particular dired-do-igrep, in 
this context. Unfortunately, igrep doesn't seem to know how to use 
tramp. Looking at igrep.el (2.112), there appears to be at least some 
support of ange-ftp built in. Does there exist a version of igrep.el 
that knows about tramp as well as/instead of ange? Or, does anyone know 
of any other way to make it work? My Google searches so far turn up 
zilch.

Thanks in advance!
