Would checking in two or three places (as proposed) seem excessive?

Sorry, this should have been:
Checks if the file is modified when the Buffer gains *focus* (like kwrite)
This presumably could be done by listening for Qt "focusChanged"
signals, though I haven't checked how kwrite does this.

Well, for example, when I start LyX I run (attached)
svn-up-to-date.sh &
Polling the server every 30 minutes could reduce further the
possibility that a merge is needed.
