I am saddened by the news that Techspansion is no more. The creators of Visual Hub (one of my faves), has officially ended development for VisualHub, AudialHub, and iSquint.

“...After much soul-searching (it's not you, it's me), for personal reasons, Techspansion is closing its virtual doors. The Support Forum and Support E-mail will be available for a while longer to take care of any remaining issues for you.”

In the last site update, they provided directions on how to backup VisualHub.
“In order to preserve VisualHub (or AudialHub) if you need to switch computers, you need to back up two things:

1: The VisualHub (or AudialHub) app itself
2: The conversion engine

To back up the conversion engine,
copy the folder at: /Library/Application Support/Techspansion

...for good measure, you can also back up your Preferences file, containing your registration info in case you lose the original purchase e-mail.

It's at:
/Users/yourname/Library/Preferences/
com.techspansion.visualhub.plist

...or for AudialHub:
/Users/yourname/Library/Preferences/
com.techspansion.audialhub.plist

As far as I can tell, the two programs will continue to work in Snow Leopard, but I obviously can't predict the future or what Apple will do in it, though.“
