oil panting conservation

[Bullwinkle]

I have an old, old, oil painting I would like to enjoy out here (heirloom - not one of those dogs playing poker - grin)- my fear is the linseed base of the paints will soon be consumed by the local zarbitees and other fungus.

Any experience in preservation out there - best I can think of is under a vacuum encased in lexan and glass - any thoughts?
