Hello steemit!
Here i am the day i predicted id have the basic functionality down.
I do. That is, enough to offer some of my space - for the moment i limited it rather heavily both in space offered for now as well as in price. I prefer to see how it scales before going all out.
Above, you see a link to a graphic newly generated whenever there is a change to the offered pricing or the available space. That is, the space currently still available. Be aware that this data is very regularly refreshed but not on access of the image itself, once its in the range of megabytes, id advise against trying to host anything more (as small as the issue might be in this case due to having quite a bit more space to offer on rather short notice).
Eventualy - id expect another week will do in terms of that becouse as soon as other users want to offer their nodes, security becomes slightly more important – ability for others to offer their space will be added. I can just edit the database directly, you cant and thus a somewhat secure web UI has to exist for you to set your stuff up.
More details on inner workings then.
How it works is rather simple, you send steem or sbd to 
The ability to upload files which arent yet part of the ipfs-network is something that is also planned, not yet existant.
The time for storage is stored as unixtime + however long it will be stored in seconds in bigint, so the 2038 year problem wont be a problem if you want to store something for longer (assuming of course the scripts run on 64 bit by that time), of course i can make little promises regarding anything that happens after my death but short of violence, suicide, an accident or medical malepractice that should be another 20 years after 2038 at least.
I have to say that i dont have a big upload bandwidth. While this will be compensated for by other nodes as soon as it is requested, the first time something is requested since any node which buffered the file collected its garbage this will be somewhat of a bottleneck, if you want something to be accessed relativly quickly, my node is currently likely not the way to go.
Illegal content will obviously be removed if and when i learn about it.
