DirecPC (Hughes) now has a business grade service called
DirecWay.  Haven't tried it.  One would expect it
would be better than the ones intended for residential only.
It claims to go to 1.5M down like Tachyon.

I use Direcway presently as my primary link. I refer to it as, "Dialup
Plus!" As a previous poster noted, ssh sessions are painful. I now resort
to typing e-mails out in a local text editor and cutting and pasting them
into my ssh window.

Here's a local traceroute performed just now at 7am on a Wednesday to a
random service like Google. Performance gets significantly poorer during
peak business hours. High d/l rates are only achievable late at night it
seems.
