Google account unit limit.

[mnielsen]

Hello,

We are building an Android app that need to update itself via Android Market. Therefore all our tablet units have a Google Account associated with it. We use the same Google account for all our units so far.

My question is:
Are there any known limits as to how many units that can have the same Google account connected to Android Market?

If so, what is it and can you circumvent it in any ways? Maybe by contacting Google or what not

Thank you for your help
