Every once in a while (though not nearly as often as software vendors
probably hope) I run across a demo that makes me think "hey, that's
pretty spiffy." The KnowNow folks put on such a show for me the other
day, and then sent me a copy of their software so that I could try it
out for myself. What they've provided is an easy infrastructure for
distributing information from Web services and other sources into a
variety of clients including browsers and Excel spreadsheets. It's a
wonderfully nonintrusive bit of middleware that works quite well.
You can see a little of the demo yourself: point a Web browser at
http://sales.knownow.com/dev/forex/index.html. What you'll find is a
page that points to a KnowNow LiveServer. The LiveServer in turn gets
its data from a Web service. When you open the page in your browser, it
subscribes to a publication from the server - and the server is quite
happy to have multiple subscribers to a single publication. There's a
bit of magic going on here with a hidden frameset, but it all works
quite well.
It gets better from there. Imagine an Excel spreadsheet subscribing to
the same data, after installing a simple add-in. Then with a few mouse
clicks you can *publish* a cell from the spreadsheet to a LiveServer in
your own organization. Then you can subscribe to it from another
spreadsheet, or a browser. As an example of HST ("hooking stuff
together") this is impessively simple.
It all works over http: or https:, so it's as secure as any other
Web-based process can be. The server also supports a bunch of advanced
features to make your life easier: store-and-forward event delivery,
LDAP/ActiveDirectory authentication, clustering and failover support,
for example. You can also configure the server to store events to
disk before dispatching them, as added security against hardware
failures. Oh, and there are versions of the server for *nix as well
as for Windows.
KnowNow offers both concurrent and node-based pricing. Some readers may
also be interested in their newly-launched Solution Partner program, which they've
designed to help start pushing their technology to market more
aggressively.
