"...good puzzle would be to cross Dublin without passing a pub".
Apparently (I haven't gone to test the theory out) a solution to Bloom's musings appeared after using a computer programme.
Some dispute still exists, in terms of ignoring restaurants and hotels where passers-by can get a drink, but still a very worthy effort, I reckon.
Check out the programmer's blog here, for details.

Where do they get the money? Coming up redheaded curates from the
county Leitrim, rinsing empties and old man in the cellar. Then, lo and
behold, they blossom out as Adam Findlaters or Dan Tallons. Then thin
of the competition. General thirst. Good puzzle would be cross Dublin
without passing a pub. Save it they can't. Off the drunks perhaps. Put
down three and carry five. What is that, a bob here and there, dribs and
drabs. On the wholesale orders perhaps. Doing a double shuffle with the
town travellers. Square it you with the boss and we'll split the job, see?
How much would that tot to off the porter in the month? Say ten barrels
of stuff. Say he got ten per cent off. O more. Fifteen. He passed Saint
Joseph's National school. Brats' clamour. Windows open. Fresh air helps
memory. Or a lilt. Ahbeesee defeegee kelomen opeecue rustyouvee
