Just another Cross-Sell mod (support thread)

[Worgazza]

I'm writing a new version of this module with some add features that I need to justify if it is worth it (in other words, will these features add benefit to you?)
Those are:
cross sell product to product (old),
product to category,
category to category,
category to product

I need to see if it is worth it or now, reason is:
To cross sell so many ways like that we will need more than 1 queries executed to pull out the products. I will consider caching but still it will use more resources that it is now. So let me know what you think. Is this worth it?

This is EXACTLY what I've been looking for - if a customer buys any product in category A - I would like to suggest non specific items from category B, C, D etc...
I can see product to category and category to category being VERY useful.
