Here is the scenario (hypothetical at the moment):
I have two papers on entirely unrelated topics, but are both presentable at the same conference. Paper 1 was funded through funding agency A, but paper 2 was not. The conference has multiple sessions covering a wide variety of topics. My funding to travel to the conference was provided by funding agency A in order to present paper 1.
Is it ethical to present paper 1 and paper 2 at this conference (given that I pay the abstract fee for paper 2 out of pocket), or am I confined to presenting results from the paper that I was funded to present?
Note: This isn't a dilemma I face now, but one a bit further down the line.
