emphasis::please note any problems, I'll try to add solutions here.::
@section{section}
1) using ProxySpace with more than one client, with separate bus spaces
@section{note}
if only one client is using a remote server, only step (a) and step (d) are relevant. The clientID argument can be left out then.

@section{subsection}
before you start
remember to synchronize your system clocks. This can be done by:
@section{definitionList}
## in macOS || SystemPreferences>Date&Time: set emphasis::"Set Date & Time automatically":: to true.
## in Linux || set the ntp clock
::
a local time server is better than the apple time server. if you cannot sync the time, you can set the server latency to
@racketblock[nil::. This will break the pattern's functionality though.
]
@section{subsection}
a) boot the (remote) server and create a local model
@racketblock[
s = Server("serverName", NetAddr(hostname, port));
s.options.maxLogins = 16; // or the maximum number of participants in the network
s.boot; // you cannot directly boot a remote server instance, but this initializes everything that is needed
::
]
@section{definitionList}
## serverName || can be any name
## hostname || is an ip address, or if you have a name resolution, a network name
## port || the port on which the server is listening. default is 57110
::
see link::Classes/Server::
@section{subsection}
b) from each client, initialize the default node and set notify to true:
@racketblock[
s.boot; // this will initialize the tree and start notification
// if needed, a server window can be created:
s.makeWindow;
::
]
@section{subsection}
c) now create a ProxySpace from the server:
@racketblock[
p = ProxySpace.push(s);
::
]
