	Is Express Window going to be to CLIM what PCL was to CLOS?

	I must confess I have not installed and used EW yet, but I recall it implement
	Dynamic Window stuff, which itself is the base for the Lisp Machine CLIM
	implementation.

	So it looks like EW and CLIM has some common points.

    That's my view.  Originally, EW was written to be a commercial product
    that brought DW type functionality to other platforms.  At about the time they
    were releasing EW for sale, it became apparent the CLIM was for the same
    purpose, but had better industry backing.  So, my guess is that is why they made
    EW public domain (i.e. free).  We are interested in using EW only because it's
    free, and my guess is that when and if we get the funding to buy CLIM, we'd be
    much better off using CLIM, because of all the obvious reasons like support, and
    later generation software.

I guess I've viewed EW as strictly an implementation of DW for other
Common Lisps.  We are looking into using EW for a couple of reasons (1)
you can't beat the price (2) it offers way to get our DW-based
applications running on other customer's hardware quickly.  Personally,
I see it as only a temporary solution until we get, then convert to
CLIM.  

The rub is, though, I need portability for some of my work not today,
but yesterday, so I can't wait until CLIM gets released for all the
vendors.  Besides, (and you can debate the logic of having done this in
the first place) we've invested a great deal of time into developing our
current DW applications.  It's tough to go ask for money to RE-do old
work.  Management is always so interested in seeing new and more
functionality.
