Product Page: Show Links to Categories where it also resides?

Hi,

I hope I'm posting this question in the correct section.
Thanks for such a brilliant shopping cart and for all the help the community members provide.

I have few products (cartridges) which are linked into many categories (printers). For example the HP No.56 cartridge will work in about 50 different printers.

I want to have a block of links underneath the products description page that shows where that particular product (cartridge) is linked or in which category (printer) it will work.

Eg. Product Part HP No 56
http://www.123-inkjet-cartridges.co.uk/hp-ink-cartridges-23/hp-cartridges-by-reference-293/black-remanufactured-hp-no-56-cartridge-19ml-230.html
... on this page below the 'buy it now button' have...
This Cartridge is Suitable to work in:-
HP Deskjet 450 HP Deskjet 5100 etc etc

All the linking details are already in the products_to_categories table - could this be used somehow to show what I want?

Thanks in advance for your help.
John
