Sync'ing works most of the time, and I do see changes reflected in the
remote filesystem.

I'm trying with two different remote targets. On is a POWER machine
running RHEL 5.6, and has bash 3.2
The other is my laptop (accessed via remote tools but from the same
machine), and it runs bash 4.1

Well, I have updated the PTP plug-ins to 5.0.0.201105180645, and things
seem to be working *much* better. In fact, the remote includes ability
that Greg Watson showed me how to do is working now as well. That's
very impressive!
I tried an example "ANSI C Hello World" project, and indexing appears to
be working fine, and it can invoke make remotely, but I think the
project is missing its Debug and Release config directories and so the
Makefiles are missing; I say this because I see this error message in
the console:
/bin/sh: line 0: cd: /home/corey/workspace_RC1_c/hw2/Debug: No such file
or directory
make: *** No rule to make target `all'. Stop.
Here's what ls -R looks like on the remote dir (.git subdirs removed for
brevity)
./
../
.cproject
.git/
.project
.settings/
src/
./.settings:
./
../
org.eclipse.cdt.managedbuilder.core.prefs
./src:

OK. I can't commit to helping out with the code until we decide on the
direction we are going with our SDK. Also, we would need to get
internal approval to contribute to the PTP project (we are in the
process of requesting it).
Nonetheless, I like this so much already, that I may advocate its use
for other things internally. In particular, I think this could be an
excellent solution for remote Linux kernel development.
