Hi,

OProfile has been used to collect data on one machine and then analyze it on another.  The oparchive command is used to package the data and related binaries for analysis on another machine.

http://oprofile.sourceforge.net/doc/oparchive.html

I don't know how hard it would be to add support to linuxtools for that.

I would imagine this workflow would be common with embedded platforms where there isn't much room for heavyweight analysis software.
