public education

Greetings!

By day I'm the Webmaster at a mid to large size public school system here in the USA (Frederick County Public Schools, MD). I'm curious to know how many of you out there in Drupal-land are implementing Drupal sites in the public education sector. Some specific questions:

1) Do you support it (server-wise) in house or do you host outside/off campus?

2) Do you host on VPS/dedicated or shared? Linux or Windows?

3) Do you run multi-site configurations?

4) How long have you been running Drupal sites?
