Ideal DL Budget

I just finished the annual report for our distance learning program, and based on the data, I've been thinking about what would be a realistic goal for a district to spend on distance learning programming (field trips, connections to experts, projects, etc.).

Our districts are fairly small, and considering the mini-grants we offer at the ISD, free programming, and free connections to other students, I think a budget of $500-1000 for the district would be an appropriate amount. Right now most of our districts put $0 towards distance learning programming due to tight funding. The district that spent the most in 2004-2005 spent $575.

This funding could come from district tech or curriculum funds, PTA/PTO funding, or other creative sources. What other ideas are out there?
