The hops are limited to the time-value which the sender wishes to pay
and the minimum acceptable timeout between each hop. It should be
relatively cheap if you game it out, though (I don't forsee me opening a
1 BTC channel and being able to make $5 per month...)
1-day is used as a convenience. However, the time between hops should be
somewhat long, as the intermediate steps can be extended further when
you want to offload the HTLCs to others who have a channel open with
both counterparties. E.g. Alice sends a payment to Dave through Bob and
Carol. Bob has a channel with Carol and has an HTLC with it, but that
channel seems to be used a lot. Erin has a relationship to both Bob and
Carol, she can offload the payment so that the payment actually goes to
A->B->E->C->D. B<->C is now completely clear.

How do you send coins if you wanted to send funds below the current
IsStandard value? It should be no different. If your wallet can't send
funds below the IsStandard value on-chain today, then I don't think it
should be able to to in the future, right? If you send funds *at* the
minimum IsStandard value today, you're probably paying really high fees,
this is a problem that exists today.
