Product renew & order expiration

[myplace2100]

Hi
I want to give customers certain period for getting product updates after they order the products.

1. Is there any setting so that i can set order expiration date for the product so that i allow download unless expiration date reached?

2. Is there a way to renew the order for the product before/after the order expires? Are there any settings for this kind of renewing by default ?? after renewing, the expiration date will be extended automatically.

So please help me about these two questions and are there any free plugin required?

joomla - 2.5.11, vm -2.6.0

If these are downloadable products then have a look through the various plugins to see if any come close to what you need, or can be extended. Maybe there is one here: http://forum.virtuemart.net/index.php?board=135.0
