I have had several replies -thanks everyone- that have mainly suggested
products like MrSID and Horizon. These products are excellent in pushing
large raster files through the Internet however they do not allow the images
to be integrated into an existing MapX geoset. The real power of our
application is that it packages all of the spatial data that a REALTOR might
be able to use on the same map.
For example, I have created several vector layers which are available with a
radio button selection like: an 8 county seamless contour map derived from
USGS DEMs, a school zone boundary map, a "sales area map" and a Standard
Flood Hazard Area Map. What I want to do is add certain raster layers
within the same app. so what I need to know is:
How large should the tiles be?
Will geotifs work or will I have to register each panel :( ?
Any pitfalls I am likely to experience?
Thanks again for the assistance and I will of course post to the list the
results of my findings after all the data is compiled.

Before you go any further check out http://www.lizardtech.com, their
product called MrSID is an image compression tool which was tailor made to
prepare data for this type work, it is still young but having looked at the
type of work you mention there is a lot to do and rather than retread your
steps later which I think will be inevitable, see if you can incorporate
this now. There are some links to splendid web sites acheiving this
internet data service although I usually use the ISDN at the office to
check this stuff I am sure it will still be efficient at 56kps. By typing
MrSID into any decent search engine brings up more links to sites
