For about $750-$1500 in parts you can set up point to point 11mb/sec link using 802.11b base-stations and high gain antennas. With a clear line of sight between stations you can extend this to at least 12 miles.
I would try to find 3 roughly equidistant points between the school and the source of your connection and bridge 3-4 wireless point to point connections between them.
Each relay station would have to have AC power and a land owner willing to let you put up a 20-30 ftp poll.
Ping times might be a little high (although probably not any worse than what you are getting on satelite right now).
As a starting point, here is a company that sells some of the raw materials.
I work for one of the "big 5" (or is it big 4 now?) consulting companies and just finished up a 6 month "study" on this type of middleware. The short answer to this question is, NO. There are no opensourced messaging middleware products currently available. As has already been mentioned, Linux is supported by a few existing commercial products:
* The MQSeries client for Linux: It's old (1997) and unsupported. I don't believe IBM currently has any plans to port the MQSeries server to Linux. Even if they do, it is likely to carry the same large ($2000-$5000) licensing costs of other Unix platforms.
* TIBCO Rendezvous: Tibco has full support for Linux in their Rendezvous product. Rendezvous is a publish/subscribe MOM product.
However, MOM products are typically used to integrate large backend legacy systems with newer systems and services. They allow you to have an OS/390 running nothing but SNA communicate with a Unix box running TCP/IP without having to learn all the "gory" low level programming details of each protocol (which usually aren't all that bad, they're just to complicated for folks who would rather write application logic:). Given that the vast majority of Linux (and *BSD) boxen run on IP networks, and that most open source developers are probably comfortable with network programming, it's not really a supprize to me that no one has found it necessary to write a general purpose open source MOM system.
Not that I would mind if someone did. In particular, an MQSeries server (or better yet, and MQSeries _compatible_ server) would be a big help in getting Linux into high end data centers.

Folks, look at:

This group, using modified RC airplane parts, made such a crossing in 1998. Their plane is now in the Smithsonian.
