[NLRS] RainScatter mobile

Friends,

I took a break from my studies this evening to work on a project that 
makes RainScatter accessible from mobile devices such as web-ready 
phones and PDAs.  I got the first stage up and running on my local web 
server.  It provides a web page that will prompt for home and DX grid.  
When that data is submitted it will spit back a simple text page showing 
dBZ, Top, Height of max reflectivity, and beam heading from home grid 
for all storms on the path.  The HTML is minimal so as not to eat 
bandwidth, but you can try it from any browser, not just those on cell 
phones and PDAs.  I'll try to leave it up as much as possible over the 
next couple of days.  The idea is to make rainscatter data available in 
the field where people usually don't have a full blown laptop to run the 
desktop version of rainscatter.

Here's the URL:
http://70.101.49.65:8080/webrs

If you want to hard-code a bookmark and skip the form altogether, you 
can manually enter the "get" request into the URL and save it as a 
bookmark.  I'll probably make some mobile java applications to make this 
a little easier in the future, but you can use the following as a 
template.  E.g., to view storms on a path from EN34lx to EN13vc:
http://70.101.49.65:8080/webrs/RainScatterServlet?mygrid=en34lx&dxgrid=en13vc 


Right now I'm only watching the following radars, but I can change these 
at request:
Grand Forks ND, Aberdeen SD, Minneapolis MN, Duluth MN, Indianapolis IN, 
Buffalo NY, Pittsburgh PA, Greenville and Greer SC, and Knoxville TN.

Let me know what you think.  For those who care, I'm using some local 
software that updates an SQL database with storm data every 7 minutes.  
The web side is running some server-side java applications to query the 
database to make the webpages you see here.  Eventually I would like to 
integrate this stuff with the current desktop application.
