rewrite multiple domains to one

I'm not sure of a good way to ask the question that I would like
answered, so instead I'll try to give an example of what I'd like to
do.

Imagine I own 3 domain names, one for each product that I sell.
http://product1.com
http://product2.com
http://product3.com

Within these domains I also have subdomains for each product, relating
to it's use.
http://sports.product1.com
http://industry.product1.com
http://games.product2.com
http://blahblahblah.product2.com
http://names.product3.com
etc.

What I would like to know is, is it possible with mod_rewrite to have
all of these urls rewritten to one domain? IOW, the first example
would become something like
http://www.diffhost.com/product1/sports
or
http://www.diffhost.com?host=product1&subdomain=sports
while the second example would become
http://www.diffhost.com/product1/industry
or
http://www.diffhost.com?host=product...omain=industry
the third would become
http://www.diffhost.com/product2/games
or
http://www.diffhost.com?host=product2&subdomain=games
etc.? I hope I've explained this well enough. Let me know if I
haven't. If anyone knows if this is possible, I'd love to hear it.

Thanks

Do you have access to the httpd.conf so that you can use RewriteRules
e.g. inside of your virtual host container?

Yes, it's our own server/s and I have full access to change anything I
want.

RedirectMatch is the simplest method.
In the <directory>
RedirectMatch (.*) http://domain.tld
