[Rd] experinental revision of the 'snow' package

[Markus Schmidberger]

Hello Luke,

at our windows cluster everything is working very well. We have 8 nodes, 
WindowsServer2003 and mpich2 (1.0.7).
Attached a small testcode and sessionInfo()

I did some bigger tests using my "afyPara" package. There were no problems.
There was an other discussion at the Rd list. Giuseppe confirmed, that 
DeinoMPI & Rmpi & the new version of snow is working very well.

See you in Seattle at the BioC2008 or Developer Day? I will fly to 
Seattle tomorrow.

Best regards
Markus
