I agree, it's very unclear what's being asked here but when a
near-instant update/trigger is needed, a hook is almost always
preferable to polling incessantly.

svn info <url> then parse the output for the bits you need.

Just to be clear, TortoiseSVN (and CommitMonitor) is almost certainly
not the right way to approach what's needed here. Command-line svn,
hooks, and possibly language bindings/DLLs/modules/packages are much
better suited to automation like this.
