Interesting about the Millenecom changing hot spot.
Another part-timer option is Verizion prepaid Jet Pack plan. Was surfing used Jetpacks on craigslist and discovered this: Prepaid Jetpack -Verizon Wireless
No activation or reconnect fees.
My family shares 8 gigs a month on Verizon currently, so adding gigs during our heavy use months isn't a big trick..
NOW HOLD THE PHONE, SO TO SPEAK
I logged into Verizon to look at monthly plans... They are listing an internet only plan that is more in line with the Millenecom plan... $20/mo device access plus $110/month for 20 gig... the advantage there is you could taper that down to 4 gig for $50/month ($20 access + $30 data) on your slack months. I also found an error on the page, and chatted with customer service about it ...they were showing $5/month in one part of the page for jetpack access and $20/month on another. He said pricing was $20/mo but it'll be interesting to see if there's new pricing in the works or if a web designer fat fingered...it was pretty glaring to me, but these things happen.

Also note that data for phone + internet is more expensive than "internet only" plans. If i was full-timing and planning to rely on the jetpack, I'd be hard pressed to add it to my existing phone plan.
Everyone confused yet?
As a part timer I'm going to consider a prepaid. One PLUS of going that way is I can start a new "month" the day I start a trip.
