>Sounds like were on the same path. Your ideas are interesting. Some sort of XML implimentation will probably be the way to go - got alot of reading to do.

How about a table on the server side that stores a record for each persisted piece of "state", with an ID identifying it for future use, and a MEMO field containing XML? Should perform pretty fast, especially with Rick Strahl's fast wwXML class to parse the XML in and out to a cursor.

Now just need a generic mechanism for identifying changed items and we're in business.

>Quiz - What country song does has this verse:

I have absolutely no idea. Most of the country songs I can remember have to do with pickup trucks ("That's not my pickup in your yard...", etc).
