con: Each copy of the swap contents means another writing process on a fairly limited amount of flash cells, eventually decreasing the cell's lifetime. But I don't think that's an issue unless you intend to keep your N900 for a decade or so.

On my 64Gb card I am thinking 2x 800Mb swap spaces, 5Gb Document partition and whatever's left for a Music partition.
Can anybody see any issues I may come across with this?
With music on the card I am hoping for smooth multi tasking while playing music under heavy load.

Music (read-only) and documents (small files, very few writes) shouldn't cause much trouble if they are on the SD card with the swap partition.

I would just use ereswap but that would defeat the object of lowering flash wear by only swapping one way.

Not just wear, this also should shorten the swapoff/on refresh slowness a fair bit since this ring moves the swap one way.
Why so? In ereswap config, you can define both main and "backup" swap as partitions on microSD ,(mmcblk1p2 and mmcblk1p3 in this case) which leaves internal swap out of use (it can even not exist) making it fully compatible with your use case
If you don't need these additional 768MB on your emmc it doesn't hurt to keep the stock swap partition anyway.
Changing between swap partitions via a cron essentially does what Estel's ereswap does if you set it up to automatically switch the partition, so it has the same pros and cons:
pro: You get a "fresh" swap every morning.
con: Each copy of the swap contents means another writing process on a fairly limited amount of flash cells, eventually decreasing the cell's lifetime. But I don't think that's an issue unless you intend to keep your N900 for a decade or so.
