Hi Alex:

There is a new feature in ESS 5.11 that might be of interest to you
http://ess.r-project.org/Manual/ess.html#New-features
Check out M-RET
Documentation:
Synchronise the current directory of the S or R process to the one of 
the current
buffer. If that buffer has no associated *R* process, provide a message.
