Does the vBulletin call-to-home Slow the site down?

[gibigbig]

Every forum creates a ridiculous amount of traffic, it worries me that vbulletin's call to home feature which is required in the license agreement, may lag on the sheer mass of the internet's traffic. Large forums like Digitalpoint may be one of the best examples.

As my experience goes, the call to home is admin panel based, which means that only admins can actually initiate the call to home process, and that is a huge relief in itself, although, vBulletin's forums are increasingly being flowered all over cyberspace,. Ultimately the question still remains.

Will there be a future lag as the vBulletin's servers gets closer to its capacitance?

For those of you who don't know, a call -to-home is a request used to verify that the copy of vb being used is valid, im not sure on the details as to if this only occurs during installation or for any time you may log in the admincp.
