With Qwest DSL, you have a choice of ISPs.  Any blocks are probably  
the work of the ISP, not Qwest as DSL provider.

I used Qwest DSL with Convergent Internet in Tempe as my ISP.  I had a  
static IP and ran several 'toy' servers out of my house for several  
years with no issues.  Great customer service and linux-friendly.
