I do this. For me it's fairly easy as I left academia and simply carried on working with former colleagues/acquaintances, in my spare time. My contribution as a %age of the overall workload has dropped, but is still meaningful.

Obvious caveats are:

* In some areas such as CS, you'll want to publish at a conference. If you submit a paper, one named author will have to agree to present it. If that has to be you, you'll have to pay the travel and registration cost for the conference.

* IP / ownership issues are big, particularly if you work for a BigCorp in a field close to that you are publishing in --- these tend to be pretty inflexible on this. I found it difficult, but not impossible at the BigCorp I worked for. I'm in a small consultancy now, and it's a breeze.
