Change in semantics here might lead to a change in behaviour.
First of let me say how much I like the general idea of what
is commenly know as fees to be called bids.
Thanks for that! I don't imagine for a moment that I could sway everyone single-handedly, but I hope this discussion helps! Until recently I wasn't 100% certain about the 'fees' really being bids -- perhaps there was some special trick or unique behaviour that made them different? But it never added up -- a 'fee' that you could alter or choose to not pay altogether, and then the request might or might not not get accepted regardless?? So now I've made this thread and hope that as many people as possible start using the more standard terminology.
All the information's publicly posted, so I don't see why it would be too difficult for a client to pull this information.
Yep. Scraping data from the block-chain blockchain.info etc. I think I've already seen a site that shows a bid vs confirmation time scatter-plot, so I think it would be nice to have something along those lines integrated into a wallet client.
It should be noted that a .0005BTC bid is not equal among miners, core rules ignored for a minute. Certain pools create certain allowances, bans, and modifiers for different transactions, as well as perhaps certain entities. The SDice patch is a good relevant example. The worrisome spat of no-tx blocks a while back is also a good example of "the rules" being modified - because the rules are more default settings than rules, as I understand it. If you made Luke-Jr really mad, for instance, he may have Eligius ignore all transactions coming from addresses known to be yours., and IIRC, Eligius is known for having irregular bid rules.
Thus, there probably isn't particularly accurate information on whether or not the particular tx you send out will be included in the next block. But, you could get a fuzzy idea using simple information, assuming everyone uses the default bid weight settings.
I guess people could even investigate individual Pools' pricing policies, so that you end up with per-pool price indicators... It just all requires time and effort, I guess.
I wonder when this becomes the rule - will the day of
bitcoin state of the art come when we have special developed
clients for each "nolonger called mining- but now payment
announcementpool" so that we bid in there personally
held auction?

Quite possible. With multi-sig transactions starting to come out, I can imagine all kinds of cool possibilities e.g.: miners gain loyal customers who have their transactions cleared exclusively through them. It's just that calling bids 'fees' so confusing!
