John, you seem to have same mistake I had.
DSL is no no in medical field.
I changed from ATT DSL to Cable only 1 month ago.
DSL has upload speed limit which is one of a characteristic of DSL !
Some companies (such as Comcast here in GA) provide a certain faster service, but my office is not coverage area.
The download 3 MB is quite good for DSL. Upload is usually 0.25 - 0.3mb/second at most.
We cannot blame DSL as it is how DSL's characteristic. I talked to att DSL tech support and I heard answer that my complained speed 0.2 - 0.3 actually is good speed for DSL, he said !
I switched to Cable (Charter cable) and download is 7 - 8 mbs average, peak is 10 and over mps, up is about 2 - 3 mb/sec.
As long as you have DSL, gotomypc also is slow. Big difference you may have is
1) Radiologist's group may not complain low upload speed froom my office: I have x-ray system with DICOM image reading at local radiologist's office.
2) Your gotomypc remote acccess becomes much faster, and now you may change your mind - "probably I can actually see patient with gotomypc at my second office..."
3) You may not suffer great system slow down when you synchronize bigger files with dropbox. With DSL, even simply moving big file to dropbox (and it starts sync immediately) causes slowdown - remember synchronization is uploading (and downloading) process.
4) When you use Saas, upload is very important as you are not saving scanned image directly imported to local server, but instead upload to cloud server !
After I changed to DSL, upload is almost instant.
