Dream clothes line?

For the minute lets ignore cost and describe your dream clothes line.

1.  Over grass so anything dropped isn't landing on dirt or in weeds.  2nd choice here would be over concrete or rock patio.
2.  Some sort of raised clean area to set baskets on etc beside one end.  This lesson learned because the current clothes line has a cistern lid beside it.  Picnic table maybe.
3.  Built solidly enough for posts not to keep from drifting in with loads over time.  Thinking 2 posts with a pipe or concrete beam buried just under the grass as a fulcrum and a cable to handle tension buried deep so the posts can't move
4.  Standard T shaped post structures with 3 to 5 clothes support wires.
5.  Stainless wires so no staining from the wires
6.  Location.  Out the most visible location, close to a door, and ideally in a wind sheltered location from strongest prevailing wind

Then if over grass with enough room would like to turn it into a volley ball, badminton area, ect.
This would require 3 addition features.
7.  Ability to rotate the T and wires to vertical so the net could be hung over them.  Might be nice to be able to hit an able between for sun drying trays.  Over center cam maybe to release the tension while moving and lock again.
8.  Ability to adjust the height of T to cover needed heights.
9.  Distance great enough to allow full net length between the posts

Clothesline material - uv resistant-coated, stranded brass. Best stuff I've ever used - doesn't rust, fray, or stretch - no stretching means it doesn't need poles to raise the middle. I Just wish it could be closer to the door. Then again, I wish my laundry rink was closer to the door, too. Instead, it's centrally located, in the house. So, I have to haul my heavy, wet laundry quite a ways. So, When it's really heavy, I only carry it to the door, then plop it into the wagon, and pull that, instead. Then, the wagon serves as my something to set the laundry on, while I hand & remove the wash from the line.

My next clothesline related purchase will be the coated stainless steel clothes pins.

I think I might have this!    Clothes line is a "Hills Hoist" rotary clothes line - looks like the internal skeleton of a big square tent: -  
https://hillshome.com.au/collections/hills-hoist-clotheslines.    Mine can be removed from the ground,   it is height adjustable by means of a winder,  and rotates freely in the breeze, but can be lowered to a fixed position for the pegging out operation.  
I have mine a fair way from the laundry (the only complaint) but my washing machine spins really fast, so the damp items aren't too heavy and in summer the clothes are dry before I get the last items in the basket onto the lines.   When it's really windy, pegging out the sheets is like trying to hoist a spinnaker!
